| Abstract: | A novel In2S3/TiO2 composite with visible-light photocatalytic activity was prepared by a chemical precipitation method and characterized by X-ray diffraction (XRD), transmission electron microscope (TEM), scanning electron microscope and UV–vis diffuse reflectance spectroscopy. Under both UV- and visible-light irradiation, the In2S3/TiO2 composite shows good photocatalytic activity to degrade methyl orange, ascribed to the absorption of visible light by In2S3 sensitizer and enhanced separation of photoinduced electron–hole pairs in the composite semiconductors. |
